The process of producing both a portrait head and a bust are the same. The only difference being the size, as a bust includes the torso.

Initially, after having taken a number of photographs and measurements with the use of calipers of his subject, David starts working with clay on an armature, a wood and wire framework, in his studio before sittings with his subject. Normally, in the case of either a head or a bust, the sittings required are about four, one hour sessions, which can take place either in his studio or where they live if more convenient.

After the final sitting, David encourages family and friends to make any comments until all are contented before the completed model is transported to his foundry for casting in bronze.
